IMPROVEMENT IN VEHlCLE-WH EELS.

Specification forming part of Letters Patent No. 209,856, dated November12, 1878; application filed October 26, 1878.

To all whom it may concern:

Be it known that I, THOMAS BROWN, of Forest Lake, in the county ofSusquehanna and State of Pennsylvania, have invented a new and valuableImprovement in Metallic Wheels and I do hereby declare that thefollowingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of side view, part insection, of my improved wheel. Fig. 2 is a transverse section of thesame, and Figs. 3 and 4 are perspective details.

This invention has relation to metallic roadwheels for carriages andother vehicles; and it consists in the construction and novelarrangementofthe double-forked metallic spokes, and the felly or rim andhub connected thereby, as hereinafter more fully shown and described.

In the accompanying drawings, the letter A designates the hub, whichconsists of an inner core, a, of wood, and the outer metallic shell, I).This shell usually consists of three parts, the flanged body-tube c, thebracingsleeve 61, and the flange-nut e. The metallic hub-case orbody-tube cis made withaflange,

at one end, and is threaded at its other end upon its exterior surfaceto receive the flangenut 0. Between the flange and flange-nut is placed,upon. the tube, the bracing-sleeve cl, which is provided with a flange,h, at each end flush with its end openings. The sleeveflanges h areseparated from each other by the smooth portion is of the sleeve for adistance equal nearly to the length of the hub.

In the inside faces of the sleeve-flanges are radial marginal notches orsockets s, of dovetail form, into which the ends of the spokes arefitted.

The spokes B are of metal, and are doubleforked, branching from a shortthick portion, m, near the middle, forwardaud backward to the rim orfelly G, as shown at l, and laterally to the hub, as indicated at l, theouter fork being usually at a greater angle than the inner or hub fork,in order that the bearing ends it of the branches may be equidistant, ornearly so, all around the rim.

The ends of the branches 1 of the inner fork are dovetailed or flangedto fit the sockets of the sleeve-flanges h, and are secured by theabutment of the tube-flange f at one end and the flange-nut e at theother end against the respective sleeve-flanges, the flange-nut e bein gscrewed home on the threaded end of the tube 0. The outer fork of thespoke is fastened to the rim or felly pieces by flangin g the ends ofthe branches to secure firm bearings, and passing through the endflanges suitable rivets or bolts.

Sometimes it is preferred to weld the spoke ends to the rim, andoccasionally it may be found desirable to make both of the flanges onthe tube a movable, or. both fixed. Any ordinary axle box may beinserted in' the wooden core of the hub. This wooden portion serves asan elastic cushion to the wheel,

which is very solid in its construction, on account of the doublebracing of the forked metallic spokes designed to resist direct as wellas lateral strain.

What I claim as my invention, anddesire to secure by Letters Patent,is-- A metallic wheel having a metal-cased hub, A, the metallic rim orfelly O, and the doubleforked spokes B, whereof the branches I spreaddirectly outward to the rim, and the branches I spread laterally inwardto each end of the hub-case, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

THOMAS BROWN.
